I made this for the Decked out for Deathly Hallows swap. My partner has recieved, so I decided to post this here along with a sort of tutorial.

Here's a pic with tissues in his mouth

and two without tissues:

To make him you'll need two pieces of felt (one brown and one white), four black beads (two small and two medium) and some clear thread. Fold your brown felt in half and cut it down the half mark. Fold that into fourths and mark the fold lines. Taking the top fold line, and the bottom fold line, fold the felt so that both pieces meet in the middle. Sew the two ends shut, but leave the middle open. Take your white felt and cut it out into the shape of teeth, sew them onto the bottom and top of the open part of your brown felt. Sew the black eyes to the top, the medium beads should be in the middle with the small beads on either side of them. Cut out two long teeth from the left over half of your brown, and sew them to the top lip of your monster book of monsters.

I hope that made sense, let me know if you want pictures of the process.
